LICENSE problem

I have installed hyperworks but have problems with license.

I have installed hw on local machine (windows) but don't know what i do wrong.

My altair_lic.dat is empty, so I don't know how to use the 'create a USER_SERVER license file' procedure.

I tried the 'set up environment variable' procedure, but didn't work.

I tried also with flex license manager and didn't work.

What do i do wrong?

When I try to open i get this:

altair license manager: license error

Cannot connect to license server system.

the license server manager (lmgrd) has not been started yet,

the wrong port@host or license file is being used, or the port or hostname in the license file has been changed.

feature: globalgridworksEU

server name: 192...

license path 7788@asus; 1055@asus;C:/Altair/hw10.0/security/altair_lic.dat

flexnet licensing error:-15,10. System error: 10061 'Winsock: connection refused'

I don't know why i get two license path. 1055 was the port number used when i had ansys installed. But now ansys isn't installed anymore.

What port do i have to choose? do i have to do something to remove the old ansys path? How do i have to modify the altair_lic.dat file to get it work?

If ttfLicenseFile.txt in the license number, why do i need the altair_lic.dat file?

The guide says that you have to modify it into:

SERVER 101.953.23.21 807d4212 7788

USE_SERVER

In my case what do i have to write? I have to write my ip address insead of 101.953.23.21 but what instead of 807d4212 and 7788?

Thanks
